There are 6 faces on a cube. Each face has an area of s^2 where s is the edge length. Therefore:
A=6*s^2=6*9^2=486 ft^2

A cube has 6 faces,
the area of each face = 9X9 = 81 square feet.
Thus the total surface area of a cube = 6 X 81
= 486 square feet.

Area of a side of the cube= 9*9 = 81
Area of the full cube = 6*81 = 486

A cube has 6 edges- each edge is a square.
The area of a square with an edge of 9ft is 81 ft^2
So, the total surface area of 6 edges is 81*6= 486 ft^2

a cube has six sides, 1 side is 9ft squared so times six =
54 squared feet. oops- sorry this is wrong, and everybody else. they actually said 486 ^2, but it is only 486. to work it out as a square you have to use a calculator to get that by using the square root of, and it comes up with 22.04540769 square feet. so to get 486 you have 6(9x9). then the square root of, to get a square 2 dimensional surface area.

one square face area of the cube is 9ft*9ft = 81 ft^2 ...
the surface is 6*(face area) = 6*(81) = 486 ft^2

SA = s^2 x 6 sides
9^2 x 6 = 486

486 square feet
Each face is 9 ft by 9 feet, for a total area of 81 square feet.
There are six faces, so 6*81=486 square feet
9*9*6=486

If 6 cm is the dimensions of the area, the floor of one area is 6 x 6 = 36 cm squared. And the completed floor is 36 x 6 = 216 cm squared. this is through fact the cube has 6 aspects. curiously adequate, the quantity of this cube is 216 cm cubed. through fact 6 x 6 x 6 (or 6 cubed) additionally equals 216.
